Several of the options you have mention are something that can be found in any desktop environment like the option to switch between open applicacions (ALT-TAB, CTRL+ALT+LEFT ARROW...) but others are new to unity. For what i have found there is no guide yet, only a couple of helping documents. Right now this are the ones oriented to unity:

But i have to add that Unity MIGHT not be the default for Ubuntu 11.04. Today i got a letter saying that the technical board in Ubuntu will be talking about if they should go with Gnome 3 or Unity so this might be good news for Gnome users until Unity gets better or until they fuse the work from unity to Gnome, making it much more better and not dividing the work between two good groups.

For me this are the best news ever if they do get Gnome 3 as default. It will save me from explaining a lot of people some of the changes in unity at the university.
